Bus connection wire forward soldering structure

A bus connection wire forward soldering structure, comprising:

• a circuit board, comprising a first surface and a second surface opposite to each other, the circuit board comprising a solder area, a docking area, and an outgoing line direction defined thereon, the solder area located on the first surface, the docking area located on one of the first surface and the second surface, and the outgoing line direction defined from the solder area toward the docking area;
• a flat cable, comprising a solder terminal, a first attaching section, a folding section, a second attaching section and a main body section sequentially coupled to one another, the solder terminal facing the docking area along the outgoing line direction and electrically coupled to the solder area, the first attaching section substantially attached to the first surface, the second attaching section substantially attached to the second surface, the folding section bent and coupled between the first attaching section and the second attaching section, and the main body section extending along the outgoing line direction;
• and
• a fixing member, covering the solder terminal, the first attaching section, the folding section and the second attaching section, comprising a notch defined corresponding to the second surface and located at a conjunction of the second attaching section and the main body section.
